I think 2 is nicer, but if you have only a single file type in the folder
(should be very common), then I believe switching automatically to 1 will be
more convenient.
BTW, I didn't get a chance yet to reply to your original mail, but I like both
suggestions very much. I remember talking about the attribute inheritance with
Axel a couple weeks ago, it would definitely be immediately useful and a great
"comming to maturity" of this BeOS feature through Haiku. :-) Putting it into
Tracker is also what I believe is best.
Best regards,
